When should you replace a circuit breaker?

I had a senior moment yesterday moving a three-way switch to a different wall. Not only was I moving the switch, I was removing a second switched outlet that was right beside it. Anyway, the senior moment arrived when I forgot that I had removed the outlet, and instead of a neutral wire coming back to the box, I had a hot wire coming back. Well, you can imagine the number of times I blew the circuit breaker trying to wire the switch back! Around eight or ten times (I never said I was brilliant, just determined. :). I only figured it out what I had done during milking last night when I do all my serious thinking. :) So, my question is, how many times can you blow a circuit breaker without breaking it? It still works now, but is there any reason to consider replacing it now while I'm aware that I put it through its paces and then some yesterday? My inclination is to leave it on line, but ? What does anyone else think?
